Hey Ibcnya, hopefully you have isolated the problem by now. One thing that you'd mentioned that caught my eye was you set the plug gap at only .022 and i would suggest trying a wider gap setting. Generally for wot bogg combined with an already weak plug you'll be pulling your hair out for days to come. I've resolved this by setting the gap to .035-.042 on a new NGK iridium plug. Note that .045 is the max that you should go.,..,.,,..,.good luck oh i'd use a min. 89 octane for premix.,.just a thought
